Several mining boomtowns sprang up in the region, including Galena, Illinois; Platteville, Wisconsin; and Mineral Point, the location of Pendarvis. During the height of the mining era, the population of Mineral Point rose to over 4,000 as people migrated to the city to work in the lead mines. Many of the immigrants who came to Mineral Point were tin miners from Cornwall, at the southwestern tip of Great Britain. Many of the Cornish"

Most other lead minerals are related to galena in some way; boulangerite, PbSbS, is a mixed sulfide derived from galena; anglesite, PbSO, is a product of galena oxidation; and cerussite or white lead ore, PbCO, is a decomposition product of galena. Arsenic, tin, antimony, silver, gold, copper, and bismuth are common impurities in lead minerals. World lead resources exceed two billion tons. Significant deposits are located in Australia, China, Ireland, Mexico, Peru, Portugal, Russia, and the United States.

It occurs in mineral veins, and when found in large masses, as in Mexico and in the Comstock Lode in Nevada, it forms an important ore of silver. The mineral was mentioned in 1529 by G.

The Roman economy was based on silver, as the majority of higher value coins were minted from the precious metal. The process of extraction, cupellation, was fairly simple. First, the ore was smelted until the lead, which contained the silver, separated from the rock. The lead was removed, and further heated up to 1100° Celsius using hand bellows. At this point, the silver separated from the lead, and was put into moulds which, when cooled, would form ingots that were to"

Instead, Scheele correctly proposed that molybdena was an ore of a distinct new element, named ""molybdenum"" for the mineral in which it resided, and from which it might be isolated.
